Rab Women's Khroma Diffract Insulated Ski Pants
Designed to meet the challenges of steep ascents and untouched descents, these protective waterproof ski trousers are purpose-built for ski touring and ski mountaineering in frigid conditions. Lightly insulated with 70% recycled PrimaLoft® Silver Insulation, the warmth is strategically concentrated around the seat and thighs to keep vital muscle groups protected without adding excessive weight or restricting movement. Whether ascending on skins or carving through fresh powder, they provide the mobility and comfort needed for alpine adventures. Crafted from waterproof Proflex™ fabric, the trousers offer the stretch and softness of a softshell with the reliable protection of a hardshell—ideal for ever-changing snow conditions.
Zipped stretch gaiters and a snap closure at the hem help to keep out spindrift while allowing for quick boot adjustments. Reinforced kicker patches offer extra durability against abrasion from skis, rocks, and ice. The deep waistband is lined for comfort and can be tailored using dual hook-and-loop adjusters, or fitted with a belt or braces via integrated attachment points. Articulated knees and a diamond gusset ensure unrestricted movement, especially when climbing steep terrain. When the pace picks up, heat can be released through zipped thigh vents. Practical storage options include zipped hand pockets and a bellows-style thigh pocket with an internal clip to keep essentials like keys secure during deep powder descents.
